A retainer for releasably locking the male and female components of a quick connector. The retainer is releasably insertible into a transverse bore in the female component and is blocked from full insertion by a projection. An extension projects from the retainer and has an aperture sized to receive the tip end of the male component, but not a radial flange on the male component when the retainer is partially inserted into the female component. Forced insertion of the male component breaks off a ring portion of the extension thereby enabling the radial flange on the male component to fully move into the female component. The retainer can then be urged into the fully latched position locking the male and female components. Lock projections on the retainer engage grooves in the bore in the female component to releasably lock the retainer in a partially inserted, shipping position in the female component and engage exterior lock surfaces on the housing on full insertion of the retainer to lock the retainer to the female component.

[ What is claimed is:] [1.] A quick connector comprising:mating male and female components;the male component having a first end portion terminating in a tip end and a radially enlarged flange spaced from the tip end;the female component including a housing having an axially extending stepped bore formed of at least a first bore portion disposed adjacent to an open end at a first end of the housing for receiving the male component therein;a pair of opposed, aligned apertures formed in the housing in transverse communication with the first bore of the axially extending bore;retainer means, slidable through the pair of apertures in the housing, for releasibly locking the male and female components together, the retainer means including:a body having an end wall and first and second spaced legs extending from the end wall; andan extension carried on the body, the extension projecting from the body of the retainer means and disposed between the first and second spaced legs of the body, the extension including frangible block means for blocking the passage of the male component completely into the bore in the female component when retainer means is in a first inserted position in the pair of apertures in the housing and permitting full insertion of the male component into the bore in the housing after separation from the body; andmeans, carried on the housing, for preventing movement of the retainer means from the first position to the second position as long as the frangible block means is attached to the extension.
